What the numbers say

Resideline tracked 373 closed sales in Sammamish over the last six months, with a median closing price of $1,650,000. That median is the midpoint of what buyers actually paid, not what sellers hoped to get, which is why it moves differently from the asking prices you see on listing sites. These are the closings Resideline tracks and may differ from complete county or municipal records. 90% of the Sammamish closings we track here are single-family houses, so these figures primarily reflect that segment, and the citywide $/sqft figure primarily reflects that segment as well. Across the 372 closings with usable living area, the middle half sold between $523 and $632 per square foot.

From market read to offer price

A market read is the backdrop. The decision still comes down to one property and one number: what it is actually worth and what you should pay. Every Resideline report opens with this same market snapshot for the subject's exact ZIP code, then gives you the property's value, the sold comps behind it, and a market rent estimate. Pricing a specific deal? The free ARV calculator, rehab cost estimator, BRRRR calculator and rental property calculator run the numbers in about a minute.

And we show our work. Every estimate is frozen while the home is for sale and graded against the real closing price after it sells. See the live accuracy dashboard for the receipts, or read how the Area Market Snapshot works.

Run any Sammamish address through Resideline and you will see the local market and the property's value together, in one report.

The local market statistics in this report are calculated from closed sales tracked by Resideline. Transaction coverage may differ from complete county or municipal records.

Every local market figure on this page is computed from closed sales Resideline tracked in Sammamish over the last six months, and is refreshed when the data is. The closings we track within the Sammamish city limits are not limited to listing-service sales: they also include foreclosure deeds, estate and family transfers, and other off-market sales that portal medians exclude, which is why 15% of the 373 closings in this window never appeared on a listing service, and the median of MLS-listed sales alone was $1,692,000.
